“ for循环”是bash编程语言的语句,它允许重复执行代码。 for循环被归类为迭代语句,即bash脚本中进程的重复。 例如,您可以运行UNIX命令或任务5次,或使用for循环读取和处理文件列表。 可以在shell提示符下或在shell脚本本身内使用for循环。 更详细信息 请看: Bash For Loop Examples In Linux for循环语法 数字范围的...
当在进入 bash 循环之前知道迭代次数时,通常使用 for 循环。Bash 支持两种 for 循环。bash for 循环的第一种形式是: forvarnameinlistdocommands ##Bodyofthe loop done 在上面的语法中: for、in、do 和 done 是关键字 列表是具有项目列表的任何列表 varname 是任何 Bash 变量名。 在这种形式中,for 语句执...
A 'for loop' is a bash programming language statement which allows code to be repeatedly executed. A for loop is classified as an iteration statement i.e. it is the repetition of a process within a bash script. For example, you can run UNIX command or task 5 times or read and process...
Similarly, programmers can use the continue statement to first exit the current repetition and then initiates the repetition to the next iteration of the loop. For example, let us use the continue statement to iterate through a range of number and when it reaches a specific number, which in ...
使用continue语句 若要继续封闭FOR、WHILE或UNTIL循环的下一个迭代,请使用continue语句。 for I in 1 2 3 4 5do statements1 #Executed for all values of ”I”, up to a disaster-condition if any. statements2 if (condition) then continue #Go to next iteration of I in the loop and skip statem...

For loop While loop Until loop This article is part of the on-goingBash Tutorialseries. Loops can be nested. Like any other programming language, bash also supports break statement to exit the current loop, and continue statement to resume the next iteration of the loop statement. ...
There are two types of bash for loops available. One using the “in” keyword with list of values, another using the C programming like syntax. This article is part of our on-going bash tutorial series. This explains both of the bash for loop methods, an
Bash for Loop to Create the Skip and Continue Loop Bash lets you create a loop that skips a specific value and continues running afterward. The code syntax is as follows: for i in 1 2 3 4 5 do if [condition] then #Continue with the next iteration of i and skip the statement continu...
